Be it known that I, RoswELL T. SMITH, a

citizen ofthe United States, residing at Nashua,

' Mechanism for Embroidering-Machines, of

which the following is a specification.

My present invention relates to embroidering-machinesofthe typegenerally known as the Heilmann or Swiss machines, wherein theseveral stitch adjustments are effected by avpantograph mechanism, the tracing-point thereof being carried over the pattern by the hand of the operator, who also operates the needle-carriages,locks and unlocks the needles, and controls every mechanical function. Since the first introduction of these machines variousfrneans havebeen devised for rendering them in part automatic. For example, it has been proposed to effect the reversal of the railway by meansof' the devices which regulatethe th read-tension, and inapplications for Letters Patent filed by me upon the th day of June, 1885, and the 9th day of July, 1886, and numbered in serial 168,237 and 207,609, respectively, Ihave shown, described, and claimed mechanism for accomplishing this purpose by the make and break ,ofan electric circuit. 'Prior, however, to the date of the invention contained in the earlier of these applicationsthere has never been, so far as I am aware, any instance in which an embroid. ering-machine of this type has been rendered entirely automaticp In both the applications referred to I have shown and described mechanism organized toaccomplish. this result, in which the minor as well .as the more important functions are effected by devices which are wholly automatic'in action. In other words, the reversal of the railway, the transfer of the needles from one carriage to the other, and the successive stitch adjustments of the tambour-fraine are all carried out by mechanical means without the intervention of any human agency. y

It is the purpose of mypresent invention to provide an improved automatic mechanism for giving the proper stitch adjustment to the tambour-frame, and for rendering said adjustment exact and accurate to a high degree, whereby the character of the work produced pointed out in the claims annexed to this not heretofore attainable.

, My inventionalso contemplatesimproved means for imparting motion to the pattern,

which will be termed the .stencilsh'eet? throughout this specification, the purpose. of

such improvement being to establish a synch' ronous relation between the forward move ment of said-stencil and the action of any one or-more of the mechanicalelements by whiclf ment of the-tambour-frame may take'place during the period when the needlesare disen. gaged from the fabric. a 1 a My invention also comprises important im-" provements in the construction and combination of the mechanical elements by which the stitch adjustments are made, whereby great :exactness is secured, and whereby, also, a simult-aneous operation of the actuating-levers in opposite directions is rendered impossible.

The main feature or most important. part of the present invention, however, consists in the positive means whereby the movement of the tambour-frame is directed and the extent of its adjustment controlled.- It is by the intervention of this element in the combi nation. that the embroidering mechanismisrendered practically and entirely automatic.

The invention consists in the several novel features of construction and combinations of parts, hereinafter fully set forth, and definitely specification. a

Referring to the drawings forming part of 7 this application, Figure lis. a view in elevation of a'mechanism embodying my invention, the line of sight being parallel with the railway of the embroiderin'g-machine.

Fig. 5 is a partial elevation of the lower portion of Fig. 1, taken from the opposite side. Fig. 6 is a detail section taken in the plane 11 y, Figl 5. Fig.7 is a detail perspective ofpart of the devices for initiating the movement of the stencil. Fig. 8 is a detail elevation of the stencildrum detached. Figs. 9 and 9" are plan views of part of a stencil-sheet.

It is my intention to connect the mechanism forming the subject-matter of the present invention to any pattern of embroidering'machine, the preferred type being that in which the reversal of the railway is effected by the pneumatic apparatus. which formszthe subject of a separate application filed by me and pending concurrently herewith,"the same being numbered in serial 232, 552. Inasmuch, however, as I may use the reversing mechanism shown in my former application, filed July 9, 1886, with equally good results, and for the reason that the present invention may be applied to any form of machine without material change, I have shown in this case so much only of the embroidering mechanism as is needed to clearly establish the connection between the operative parts.

In the said drawings, the reference-numeral 1 designates one side of the railway of any suitable type of embroidering-machine, upon which a needle-carriage moves upon each side of the web, one end of one of said carriages being represented at 2, said carriage being drawn toward the tambour-frame by Weights in the usual manner, while its retrograde movement is produced by a belt, 3, moving in a slotted .projection, 4, on each end of the carriage, and having a driving-block rigid on said belt, in the manner shown in my application filed July 9, 1886, Serial No. 207,609. Upon the central portion of the railway is a standard, 5, forming part of a rectangular frame within which the tambour-frame is sus pended. I have indicated the presence of these parts by dotted lines, inasmuch as they form no part of the present invention and may or may not be of novel construction and arrangementthemselves. Thetambour-frame referred to is moved to give the required stitch adjustments by a pantograph mechanism of substantially the same construction as that heretofore employed in machines. of the Swiss type and others.

Upon one side of the machine and about opposite the structure supportingthe tambourframe I erect a standard, 6, upon which the operative parts of the mechanism embodying myinvention are supported. Projecting from the upper portion of this standard toward the end of the tambour-frame is a bracket, 7, of cruciform shape, upon which are arranged a horizontal and a, vertical slide-bar, (denoted by the numerals 8 and 9, respectively.) Of these slide-bars the former is mounted in bearings 10 on the ends of the long arm of the bracket,

while the vertical slide is carried in similar bearings, 11, on the cross arm. In both cases sufficient frictional contact is insured to retain either part in any position to which it may be adjusted. The bearings 11 are projected forward far enough to bring the vertical slide in front of the horizontal with suflicient intermediate space to admit the parts carried by said bars, as shown in Figs. 2 and 3.

Upon the horizontal bar 8 is rigidly mounted a cross-arm, 12, having a true vertical position and provided with a slot, 13, extending nearly from end to end of the arm. Upon the vertical arm 9 is mounted,in a similar manner, a cross-arm, 14, having a true horizontal arrangement and provided with a slot, 15,which is coextensive with that in the arm 12. These arms are mounted upon the inner or adjacent faces of the slide-bars carrying them, and when in their normal position they cross each other centrally at right angles, as shown in Fig. 1. In the space intervening between the adjacent faces of these cross-arms is intro duced the extremity 16 of the motor-arm of the pantograph. Mounted in the end of this arm is a pin, 17, projecting on both sides of thearm and having one end lying in the slot 13 and the other end in the slot 15 of the vertical and horizontal crossarms, respectively.

This pin corresponds to the tracing-point of the pantograph, which is usually held in the hand of the operator and made to traverse the pattern.

Itwill readily be seen that by adjusting the vertical and horizontal slide-bars 8 and 9, one or both, the pantograph may be actuated and movement .in any direction imparted to the tambour-frame, the extent of such adjustment being exactly proportional to the degree of movement imparted to the slide-bars. example, a longitudinal movement of the bar 9 will carry the arm 16 vertically in either direction, the pin 17 moving in the slot 13 of the cross-arm 12, while in the same manner a IFO For

XIO

movement of the horizontal bar 8 will give place simultaneously, in which case the line of movement will be the diagonal resultant of the combined vertical and horizontal adjustment.

Upon the edges of each of the slide-bars 8 and 9 are formed or mounted oppositelytoothed racks 18 and 19, the pitch of the teeth of the former being such as to give motion in one direction by the reciprocation of an engaging sp'ring-actuated pawl, while the teeth of the rack 19 upon the opposite edge have the opposite pitch. The length of these racks is commensurate with the extent of movement required for the adjustments of the tambour-frame, and they may be formed at any convenient part of the slide-bars or upon attachments to said bars.

IIf;

svmlo g s Above and below the horizontal slide-bar 8 are mounted bell-crank levers 20, so arranged that the extremities of their vertical arms approach the toothed edges of the bar. Upon the upper bell-crank is pivoted a pawl, 21, normally engaged with the rack 18 by the tension of a spring, 22. A similar pawl, 23,

'is carried by thelower bell-crank, its nose being turned in the direction opposite to that of the pawl 21 to engage with the rack 19, having teeth of opposite pitch. Each bell-crank is acted upon by a spring, 24, connected to its horizontal arm,by which the lever' is swung back after each forward movement of the pawl carried by it. i

Upon a bracket, 25, projecting past the lower end of the vertical arm 9, are mounted two levers, 26 and 27,the former being a simple lever of the first order, and the latter a compound lever composed of the two parts 32, by which their opposite extremities are retracted after each reciprocation of the pawl.

The power ends of these levers project beyond the standard 6 and are curved to bring them into different vertical planes, and a similar construction is applied to the horizontal arms of the bell-crank levers 20, all four projecting extremities being arranged in substantially the same vertical plane when viewed from the point of sight in Fig. l, but in different vertical planes when'viewed from a point removed ninety degrees from that in Fig. 1, as shown in Fig. 2.

Upon the standard 6, beneath the power ends of the levers described, are mounted brackets 33, within which'are supported five vertical bars or rods, each capable of independentver-, tical movement in the bracket 33. Of these four are motor-bars, and are designated by the letters a, a a", and (1*, the two first being arranged to abut against the power ends of the levers 26 and 27, and the two latter engaging with the horizontal arms of the bell-cranks 20,

as shown in Figs. 1 and 2. The fifth rod, 34,

has a wholly distinct function, which will presently be described. The two longer bars, a

and a, receive support from a third bracket,

35, a free movement being at the same time permitted in either direction. By the repeated reciprocation of the lettered bars the levers operating the slide-bars 8 and 9 are actuated, and movement in corresponding directions is given to the motor-arm 16 of the pantograph.

Upon the lower portion of each of the live bars is a studor tooth, 36, which rests on the lower bracket 33 and supports the bars when not in action, and upon these studs rest-s a rod,

37, carried by an arm, 38, pivoted upon the standard 6 in rear-0f the motor-bars. To the ors 46.

arm 38 is pivotally connected a link, 39,0011;- nected at its lower extremity to a latch,'40.

It will "be seen that by the rise of any one of 0.

the" five bars the arm as will be ,liftedand communicate a like movement to the latch 40.

Projecting from the standard 6 toward the railway 1 is a bracket, 41, upon the end of whieh is pivotally mounted a platform, 42,'the forward extremity of which rests upona shaft, 43, havingan eccentric, 44, by the rotation of which a. reciprocating movement is imparted to the platform, which rocks upon its pivotal point 45. Upon the outer end of the platform 42 are mounted on pivotal supports five independent selectors, 46, arranged beneath the ends of the bars 34 a a &c. The ends of the bars and of these selectors are so formed that forward normally and brought under the motor-bars by springs 47, and from the.lower bracket 33 depends a yoke, 48, which lies in front of the selectors and beneath forwardlyprojecting lugs 49. mounted thereon. As the" the platform 42 falls, these lugs engage at or near the lowest point of vibration'with the yoke and drawall the selectors back, thereby breaking the engagement of any one or more of them with the motor-bars.

Upon the forward'end of the platform 42 are:

arms 50, between which is rigidly mounteda drum, 51, havingits peripheral surface infront of and in convenient proximity to the select- This disk". iskeyed to av This drum is constructed'in two parts the drum-sections, as seen inFig. 6, and upon ,7

one end of said shaft is'a'ratchet, 55, rigidly mounted. The end of the shaft projects be yond the ratchet and carries a vibrating arm,"56,' upon one end of'which is mounted a V pawl, 57, drawn by a spring, 58,into operative engagement with the teeth of the ratchet. I 5

Upon' the same side of the pivotal'axis ofsaid bar is swiveled a sleeve, 59, through which projects a pitman, 60, which receives reciprocation from a wrist-pin on a disk, 61, carried by the shaft 43. Upon this pitman is mounted an adjustable boss, 62, which at each reciprocation of the pitman will impinge upon'thev end'of the sleeve59, and, provided the end of I the arm 56 is retracted sufficiently, will vibrate said'arm and throw the pawl far enough to turn the ratchet 55 one or more teeth. Unless,

however, this retraction of the pawl-carrying. end of the vibrating arm 56 takes place, the' pitman 60 will simply reciprocate in theswiveling sleeve 59 without effect upon the ratchet.

or more of the lettered motor-bar's a. of, &c., rise, the latch 40 will be lifted, the vibrating arm 56 will retract the pawl 57, and the pitman 60 will immediately advance the ratchet 55, thereby turning the shaft5i and the toothed disk 52 keyed thereon. This action will be repeated as often as any one of the five vertical bars is operated by its selector 46.

Over the drum 51 is carried the stencil-sheet 64, by which the action of the motor-bars and consequently the movements of the motor-arm of the pantograph are directed and controlled. This stencil consists of a narrow sheet of any suitable material, thin brass being preferable. In this sheet is formed a central series of pen forations, 65, which engage with the teeth 53 of the disk 52. Upon each side of this line are formed two separate series of openings, Z), 5-, b and 5, corresponding in transverse arrangement with the position of the selectors 46. Upon each of these selectors is pivoted a finger, 66, supported and guided by a bracketplate, 67, mounted on the platform. These fingers are of such length that when the selectors are thrown back their points will lie just a little withdrawn from the surface of the steneilsheet as it lies upon the drum 51. In the latter are formed openings 68, so situated that the ends or points of said fingers may enter the same after passing through the openings 1) D 850., in the stencil. As the platform 42 rises, lifting the lugs 49 of the selectors off the yoke 48, the selectors will rock toward the drum and the finger-points 66 will rest upon such portions of the stencil-sheet as happen to be imperforate at the point of contact. In this event the engagement between theselector and the motor'bar will be impossible. Should, however, any one of the openings 1) Z)", &c., present themselves to the finger-points, this engagement will be effected and will be repeated as long as the stencil-opening continues to present itself to the finger.

\Vithin one section of the drum 51 is arranged a sleeve, 69, loose upon the shaft 54, and having an arm, 70, which projects through a peripheral opening in the drum'section and carries an angular boss, 71, upon its end, lying partly in the opening in the drum, but having its end projecting beyond the end of the drum. In a cavity in the end of the sleeve 69 is a spring, 72, bearing against the disk 52 and giving sufficient frictional contact to prevent .backlash or displacement of the feeding-disk 52, while at the same time it holds the arm 70 in any position given it. The opening 73 in the drum, in which the boss 71 lies,is of such length as to permit said boss to rise a short distance; but when in its normal position, as in Fig. 1, it lies directly in front of the finger 66, mounted on the selector, whichlies beneath and operates the bar 84. As explained hereinafter, the organization of parts is such that the stencil-sheet, which is provided with a transverse imperforate portion between each transverse set of openings, will always, when at rest, present one of these imperforate portions to the points of the fingers 66. \Vhen in this position, with the boss 71 in its place, none of'the selectors can make an engagement with any one of the bars operated by them, since at each forward vibration of the selectors 46 four of the finger-points 66 will rest on the imperforate portion of the stencil, while the fifth will strike the boss 71.

Upon the pivotal axis is fulcrumed a le ver, 74, one end of which lies just beneath the projecting end of the boss 71. The other or power end extends to a point near the rail of the embroidering-machine, and is perforated to receive a vertical bar, 75, mounted in any suitable supports by which it may have vertical movement. On this bar is a boss-nut, 76, overlying the end of the lever, and upon the upper end of the said bar is acam-incline, 77, which lies beneath a tripping-point, 78, car-. ried by the belt projection 4 of the needle-car riage. The purpose of this arrangement is as follows: The stitch adjustments of the tambounframe must necessarily be initiated at the time when the retrograde movement of either needle carriage has wholly withdrawn the needles from the web, and in order to make the automatic action complete it is requisite that the said movement should be timed by the said needle'carriages. This is therefore the function of the bar 34, actuated by the outer member of the series of selectors 46, the operative engagement of the latter with said bar being permitted by the recession of the car riage, which trips the lever 74 and throwsthe boss 71 upward, leaving an open space,within which the finger-point on the outer selector may enter. This having taken place, the selector raises the bar 34 with the upward movement of the platform, thereby raising the arm 3S, lifting the latch 40, rocking the arm 56, by which the feed-pawl 57 is retracted, and thus causing the pitman 60 to throw said pawl forward and turn the feeding-disk 52. This advances the stencil-shceta single step, removing its imperforate portion from over the openings 68 in the drum-sections 51, and bringing the end. of one, or it may be two, of the openings b 5 &c., into position to expose the openings 68. At the next ensuing reciprocation of the platform the finger-points 66 of the proper selectors 46 enter the said openings, and an operative engagement being thus made between their selectors and the corresponding motor-bars, a a", 850., the stitch adjustment of the tambour-frame is initiated. The first step movement of the feed-disk 52 brings the boss 71 back to its normal position, and thereby excludes thefeed'finger from the opening in the drum, throwing the selector carrying said finger out of action. The successive feed movements of the stencil are, however, continued by the suceessive rise of the motor bar or bars called into action by the openings presented by the stencil.

The several racks on the slide-bars are so toothed and their actnating-pawls have such throw that at each reciprocation of the motor- 3O of the pawl rides up as the bell-cranks make bar in action the tambour-frame is moved exactly the distance of a single stitch, which is equal to the thickness of the needle making the stitch. quiredby the exigencies of the design, the stencil-opening is of such length as to permit but a singleengagement between the selector and the motor-bar. Adjustment of greater length and requiring repeated action-of the motor-bars will be provided for by increasin the length of the stencil-openings proportionately. be controlled by the relative transverse arrangement of these openings. As illustrated, the series b of the stencil will control the downward movements of the pantograph-arm, the series I)" the upward movements, and the remaining two series; the right and left horizontal movements, respectively. Therefore, openings in the same transverse line can never be brought into adjacent series. It isunnecessary to explain that as the platform falls after each lift of the selectors the fingerpoints 66 are all withdrawn from the drum and stem:

cil to permit the unimpeded feed movement of the latter between .successive actions of the selectors.

In order to insure the'exact action'of the pawls 21 and 23, I mount upon any suitable support a steel plate, 79, upon which the nose their retractile vibrations. As the pawls are thrown forward, they ride oft the plates and drop into the teeth of the racks, the plates being so located that after each step movement the next ensuingtooth shall liein position to engage the pawl the instant it falls from the end of the plate. If desired, these plates may be made adjustable, so'that the effective throw of the pawl may be varied.

To provide against the risk of damageshould the mechanism be accidentallystarted when the stencil is not on the drum, I mount on one infinitely varied'in the relative arrangement and length'of its openings, whereby an infinite variety of designs may be worked out by the automatic adjustment of the tambourframe, combined with the action of the embroidering mechanism proper. This stencil constitutes the directing power of the entire mechanism, and by the endless combinations of its four series of openings designs of the utmost intricacy and beauty may be successfully and automatically worked out. The perfect accuracy of mechanical action" as com- If a single movement only is re-' The direction of the adjustment will pared with the work of the skilled operative,

In both my former applications mentioned" herein I have shown a stencil fora purpose similar tothat herein described. In these cases, however, the stencil controlled thestitch adjustment by the make and break of separate electric circuits. I make no claim in the present case for this specific method of applying the stencil,nor for the several specific combinations in which it stands as an element in either of said applications. I i g It should be noted that the stencil form ing part of my invention, whether it beflconst'ructed as shown in the accompanying draw-- ings or in the manner last above mentioned, 'adm-its of but four effective series of openings by which the vertical and horizontal adjustments are directed. All stitch adjustments in lines other than a vertical and horizontal I are resultants'of these two movements combined, whether acting separately or simulta-v neously. It must be remembered, also, that in preparing the stencil adjustments .inoppo- 7 site directions must invariably be efi'ected by openings indifferent transverse series in the stencil.,. For example, the'upward and down ward movements cannot have. "coexistence in the same series of openings, having regard to the transverse arrangement.

A ny movements in lines'at right angl'es'to each other may be made simultaneonsly,and the openings representing and directingsuch' adjustments may lie side by side. in the sten- IEC oil; but opposite adjustments mu'st beg'overned by openings cut in successive'transverse' series, and this rule is without exception. 1

The operation of the machine is briefly as follows: The web being stretched upon the tambour-frame and the latter connected with the pantograph apparatus in the usual man-5* ner, the stencil 64:is carried over the drum 51 and stretched or in any way drawn down upon the drum, so that the teeth 53 engage with the central openings, 65, in the stencil.

The needles beingarranged in the jawsof one "of the carriages and threaded, the mechanism is ready for operation. The power-shaft being set in motion, rotation is imparted to 'theshaft 43, whereby a continuousrise and fall ofthe platform 42 isproduced, together with the parts carried thereby. At the same time'the tambour-frame'. As the needles leave the fabric, the tripping point 78 on the carriage drives down the bar 75, tripping the lever 74 and raising the boss 71. The selector beneaththe bar 34 is then at liberty to rock under and make engagement with the said bar, its finger 66 entering the recess lately occupied by the boss 71. The bar 34 is thereby lifted,operating the latch 40 and initiating the movement of the stencilsheet, whereby the transverse imperforate portion moves off the openings 68 in the drum, causing one, or it may be two, of the openings 1), b, b", or b to present themselves to the fingers 66 and uncover one, or possibly two, of the openings 68. Upon the next lift of the platform the finger 01' fingers corresponding with the opening or openings presented to them pass into said openings, permitting the selectors to engage the motor-bars a a a and operate their levers, thus giving a single stitch adjustment to the tambour-frame. The platform now sinks, and the finger-points being retracted by the yoke 48, the pitman advances the stencil-sheet 64 a single step, after which the platform is again lifted. If the opening in the stencil continues to present itself to the same finger, the engagement of the selector and motor-bar is repeated and the adjustment of the tambour-frame is carried a single step farther, this being followed again by a progressive movement of the stencil. This operation continues until an imperforate portion of the stencil presents itself to the fingers 66. This at once throws all the selectors out of action, and consequently checks the advance of the stencil by the failure of the latch 40 to lift the horizontal bar 63 on the end of the vibrating pawl-carrier 56. The boss 71 having been restored to its normal position immediately after the first lift of the bar 34, all operative engagement-of any one of the selectors 46 is pre vented until the next passage of the needlecarriage over the end of the tripping-lever 74. The latch 40 is pivoted on a boss, 83, projecting from the standard 6, and the shaft 43 is mounted in a solid bearing, 84, on the standard 6; but these minor details of construction may be considerably varied, as circumstances may require.

By the term selectors as used throughout this specification I refer to the pivotallymounted fingers 46, which at each reciprocation seek to make engagement with the m otorarms 34, a, a, a and a, such engagement being timed and controlled by the stencil. At each advance of the latter said devices select from the motor-arms those which are required to act in order to give the necessary adjustment.
